PROTECTIVE COATING- IFOR MEDICINAL PURPOSES,

No Drawing".

To aZZ w 710m it may concern Be it known that 1, James L. Down, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Protective Coatings for Medicinal Purposes, of which the following is a full clear and exact description.

This invention relates to a new and useful composition of matter and has particular reference to a composition for lining a cavity in a tooth.

The present invention contemplates the provision of a liquid composition for lining a previously cleaned cavity in a tooth before the same is filled in the usual or any approved manner.

Some of the objects of the present inven tion are to provide a lining composition of the aforesaid character which shall be a non-conductor of heat and cold and which shall be impervious to acids sometimes present in some filling compositions; to provide a lining composition which shall be of a liquid nature and which may be easily and quickly applied to the cavity; to provide a lining composition which shall consist of few ingredients which are inexpensive and which may be readily mixed to form the aforesaid composition; while further objects and advantages will appear as the description proceeds.

In. preparing my composition I mix together the following ingredients in substantially the proportions specified:

Mastic 50 grains. Gutta percha 180 grains. Amyl acetate 1 drachm. Chloroform 6 drachms.

The mastic is first dissolved in the amyl acetate to form a substantially saturated solution and the gutta percha which is preferably of the white variety is dissolved in the chloroform to form a second substantially saturated solution. The mastic-amyl acetate solution is then added to the gutta percha-chlorform solution to form approximately an ounce of my liquid composition which then ready for use and may be conveniently applied to a previously cleaned cavity by a broach.

The mastic serves as an adhesive and retains the gutta percha on the walls defining Application filed May 26, 1922.

the cavity. The amyl acetate not only func tions as a suitable solvent for the mastic but also retards the evaporation of the chloroform in the composition as it rises tothe and also resists any acids which might be present in some fillings of a cementitious character. The chloroform serves as a sol vent for the gutta percha and is also desirable as it imparts a soothing efiect to the tooth when the lining composition is applied to the cavity.

My lining composition is particularly valuable for lining a cavity in a tooth in which the nerve is still alive as the chloroform imparts a soothing effect thereto and the gutta percha which forms the lining, serves as a barrier to sudden changes in temperature which ordinarily are readily conducted by the filling to the nerve.

While my lining composition serves as a protective coating for the cavity of a tooth I also find that it may be successfully used as a protective coating for cuts, burns, or wounds where it is desired to prevent infection.

Having thus described my invention, what I claim is:

l. A protective coating for medicinal purposes comprising a large proportion of a saturated solution of gutta percha and a relatively small proportion of an adhesive for said gutta percha.

2 A protective coating for medicinal purposes comprising the following ingredients in substantially the proportions specified:

Mastic 50 grains. Gutta percha 180 grains. Amyl acetate 1 drachm. Chloroform 6 drachms.

3. A protective coating for medicinal purposes comprising gutta percha, a suflicient quantity of a low boiling point solvent for said gutta percha to form a substantially saturated solution therewith, mastic, and a solvent for said mastic, the mastic and solvent therefor forming a relatively small proportion of the whole.

4. A protective coating for medicinal purposes comprising a relative small proby volume of a saturated solution of gutta portion of a substantially saturated solupercha and chloroform, and one part by tion of mastic and amyl acetate, and a Volume ofasaturated solution ofmastic and 10 major portion of a substantially saturated amyl acetate. 5 solution of gutta percha and chloroform. In testimony whereof,- I hereunto aflix my 5. A protective coating for medicinal signature. purposes comprising substantially six parts JAMES L. DUSEK.
